A living timeline of complexity economics research — tracked researchers, verified sources, broad topic search
WEHIA XXX merges with the Econophysics Colloquium in Ancona — The 30th Workshop on Economics with Heterogeneous Interacting Agents ran jointly with Econophysics Colloquium 2026, consolidating the two main European complexity-economics meetings.
SFI Press publishes The Economy as an Evolving Complex System IV — Two volumes, 31 chapters, edited by del Rio-Chanona, Pangallo, Bednar, Beinhocker, Kaszowska-Mojsa, Lafond, Mealy, Pichler, and Farmer — the first installment of the field-defining series since 2006, free to download.
Macrocosm scales complexity economics into industry — Doyne Farmer's Oxford spin-out builds agent-based digital twins of the energy transition, with projects for Clean Prosperity (Canada), Aioi Nissay Dowa (Japan), and an NSF-funded global energy investment platform.
ECB folds climate risk into the EU-wide stress test — Macroprudential Bulletin 32 extends the 2025 EU-wide stress test with firm-level transition and physical climate risks — system-wide climate-financial amplification moves from research into supervisory practice.
Hidalgo publishes The Infinite Alphabet — Cesar Hidalgo's trade book (Penguin) distills two decades of economic complexity research into laws of how productive knowledge grows, diffuses, and decays.
SFI Complexity Global School convenes in Bogota — Roughly 60 students at Universidad de los Andes for the 12-day school on complexity approaches to economics and governance, under SFI's Emergent Political Economies program.
Agent-based modeling gets its Journal of Economic Literature moment — Axtell and Farmer's 90-page survey appears in JEL — a mainstream-legitimacy milestone the community dubbed "ABM comes of age" — amassing 200+ citations within a year.
SFI Reimagining Economics winter school, Abu Dhabi — The SFI-linked winter school on reimagining economics is slated for January 2027 in Abu Dhabi; program details not yet publicly confirmed as of August 2026.
Farmer's own focused review of quantitative ABM for macro — the paper you're reading first
The comprehensive ABM survey — Axtell & Farmer's definitive JEL review
The accessible entry point — Farmer's popular book on complexity economics
Complexity economics applied to policy — Wright's Law + energy transition
The manifesto — frames the entire complexity economics program in 2 pages
Elegant empirical result showing mechanism > rationality in markets
Universal scaling law for price impact — data collapse elegance
The "market ecology" framework — intellectual backbone of Farmer's program
From the Tsinghua group behind EconAgent: natural-language economic hypotheses compiled into executable ABM experiments — an early glimpse of AI-automated computational economics.
ABM supporting the UK's Seventh Carbon Budget — a concrete marker of agent-based modeling entering national climate-policy machinery.
Sakana AI: memory, tools, and reasoning as swappable components — the controllability infrastructure the LLM-ABM wave has lacked.
del Rio-Chanona and ILO economists reconcile the conflicting AI-labor exposure estimates, which now converge on high-wage cognitive work.
Oxford team makes economic ABMs end-to-end differentiable — gradient-based calibration and integration with deep-learning pipelines.
Princeton-led: a mechanism-designer agent optimizes tax policy over persona-conditioned LLM worker agents — the strongest bridge yet between generative agents and public economics.
Hidalgo and Stojkoski give economic complexity metrics a unified theoretical foundation after two decades of empirics — a likely anchor citation for the subfield.
LLM agents with memory and heterogeneous personas reproduce human expectation-formation in macro survey experiments — a cheap synthetic-subjects lab for expectations research.
Targeted rewiring of firm-level supply links cuts systemic risk substantially without reducing production — a rare actionable network-policy result from CSH Vienna.
Recasts export diversification as an explicit optimization problem — economic complexity moves from descriptive diagrams to prescriptive policy tools.
First stress test coupling firm-level supply-chain contagion with bank balance sheets using nation-wide emission estimates.
Banca d'Italia / IIASA open-source Julia engine for Poledna-style data-driven macro ABMs — lowers the entry cost for central-bank-grade ABM forecasting.
NeurIPS 2025 — 1,000 LLM trader agents endogenously reproduce fat tails, volatility clustering, and self-fulfilling bubbles. Flagship of the LLM-econophysics convergence.
Input-output model + occupational-mobility network traces which workers face frictions in a 95%-by-2035 US power decarbonization (12 jobs created per job lost in scale-up).
